IMPROVED OAR-COUPLING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, G. W. SHINGLETON, of Auburn, in the State of NewYork, have invented new and useful improvements in Car-Couplings; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the accompanyingdrawings, and tothe letters of reference marked thereon, in which-Figure 1 is a side elevation.

Figure 2, a front view.

Figure 3, a section of the mouth of the coupling; and

Figure 4, a view of the connecting-pin.

The object of this invention is to furnish a sure means of automaticdisconnection in case of accident, and its peculiarities consist in theemployment and combination of such devices as will be hereinafter fullyset forth.

As will be observed from the drawings, my coupling consists of twoparts, A and A. A represents simply a flared-mouth box, provided withthe pin z', fully shown in fig. 1. A is also a box of similarconstruction, the

back end of which rests against the spring e, which may be either ofmetal or rubber. This spring is confined in the box d, a section of.which is indicated in fig. 1. Said box comprises a portion of thearrangement which retains the coupling in its proper place. a a arestops on the coupling, which play between the bolts 6 b and the box 01.13 represents a treadle, the peculiar shape of which may be traced bythe assistance of the red lines in fig. 2. To the lower end of thistreadle is attached the cross-bar or handlef. g is a post, attached in asecure manner to the under side of the coupling A. it represents a slotin the treadle. L'is a large-headed screw or bolt which passes throughthis slot into the post 9, thus allowing, as it will be observed, thetreadle B to play up and down, and yet holding it firmly in place. is krepresent semicircular levers, which are pivoted.

.or hinged to coupler A by means of cars m m, (see fig. 1.) The lowerends of these levers pass through a slot in the foot of treadle B asshown in fig. 2; their upper ends are formed at right angles to theirbody, and extend almost through slots in the coupler A, as seen in fig.2, red lines. On each side of the mouth of this coupler are the flatsprings it 12., one of which isshown in fig. 3. The upper ends of thelevers k 70 rest against these springs, the object of which will be morefully seen hereafter. D represents the connecting-pin, which,

as it is observed, is made of two distinct parts, and pivoted near thecentre like a pair of shears. x is a spring for the purpose of keepingthe pin open, as seen in fig. 4. One end of each of the parts of thispin is bevelled towards each other, and each, also, is provided with ashoulder. Near their opposite ends they are provided with a slot; oneside of one of these slots is oval, the other straight, but they are soplaced in relation to each other that the oval side of one will comeover the straight side of the other. Thus, as the cars are windingaround curves in the track, the pin will accommodate itself to thecurve, and thereby prevent any. disconnection of the cars.

The operation of my invention is as follows: The couplers A A beingproperly secured to the cars the connecting-pin is then properlyadjusted, and held by means of the ordinary pin passing through it. Hitis desirable to connect the cars, all that is necessary is to back. themuntil the bevelled ends of the pin pass into the mouth of coupler A. Theshoulders being forced apart by means of the spring a connection is atonce formed.

In case of accidents this coupler will be found invaluable, as themoment one car is thrownfrom the track it at once becomes disconnectedfrom the balance of the train, which, in many instances, would save bothlives and injury.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The levers 70 7c, in combination with the treadle 13, operatingsubstantially as and for the purpose set forth.

2. The springs n it, when operated upon by levers k k, as and for thepurpose specified.

3. The pivoted connecting-pin, when constructed and used substantiallyas and for the purpose described.

In testimony whereof I set my signature in presence. of two witnesses.
